The invention provides a multi-dimensional biological characteristic information security authentication detection method. The security authentication detection method comprises the following steps: identifying type combination, improving security level, identifying and judging, and passing authentication. The multi-dimensional biological characteristic information security authentication detection method is reasonable in design, the security level can be changed along with the unrecognized time length. Therefore, the security can be effectively improved. The recognition types of all the security levels can be freely combined and set, and the security is further improved.
